Luméa Shell Blanks are produced by experienced craftspeople, who are experts at navigating around the spiraling cone shaped shell. Trochus shell have three technical terms which identify the area from which the blank is cut – Yoko, Mimi and Ten. The top and/or bottom is ground down to specified thicknesses and the pink and white skin can be left on, or removed creating a beautiful natural product with strong iridescence.
